Ice dams are not a Rochester problem so much as a New Hampshire one, and they show up on the same handful of eaves and valleys year after year. As part of our complete Rochester winter roof services, crews handle commercial roof snow removal across Strafford County.
Why Rochester Roofs Dam Up: Deep Cold and a Long Snow Season
The defining feature of a Strafford County winter is persistence. It is not one storm, it is a continuous load sitting on the roof from late fall through to a spring thaw.
Every mild afternoon through that stretch releases a little meltwater, and every cold night sets it at the overhang. Done fifty times, that is how an eave ends up carrying several hundred pounds of ice by March.
Ice-barrier practice in Strafford County
Because the ice here does not stay near the edge, the New Hampshire requirement generally runs the membrane well up the roof plane. On a house in Rochester roofed a few decades ago it is frequently missing entirely.
Commercial Roof Snow Removal in Rochester: How The Work Runs
Storm routes and standing contracts
Properties on a standing contract get a scheduled clear after each qualifying snowfall, with a single point of contact and a condition report per visit. For a portfolio, that means the clearing order is decided in advance by risk rather than by whoever calls first during the storm. Ceiling Sagging or Bulging After Snow.
Reduction, not bare deck
The goal is to bring the load under threshold safely, not to scrape a roof in Rochester clean. Clearing is balanced across the deck so load is not shifted onto one bay, drains and scuppers are opened so melt has an exit, and a cushion layer always stays on the membrane.
Where the figures call for it, crews bring in crane-assisted picks instead of adding bodies to a roof that is already carrying too much.
Mid-span is where the margin runs out
Long-span steel and open-web joist roofs carry least where the drift is deepest. The average depth across the field is not the number that matters; the depth over the longest unsupported span is.
That is where crews measure on a Rochester building, and it is why two roofs with the same snowfall can be in very different trouble.
The cost of a shutdown against the cost of a clear
Clearing a large deck is a real number and it is easy to defer. The comparison that matters is not clearing against nothing, it is clearing against the day the building is closed while an engineer inspects it - lost trade, displaced tenants, and an insurer asking what was done beforehand.
The load reading is what makes that decision for you rather than a feeling about how deep the snow looks.
Reduction to a threshold, not a bare deck
The goal is bringing the load under the structure's capacity safely, with a cushion layer left on the membrane throughout.
Scraping a commercial Rochester roof to bare membrane costs more, takes longer and risks the roof covering for no structural benefit.

Where We Dispatch Around Rochester
Crews working Rochester cover the adjoining communities on the same route — Barrington, Center Strafford, Madbury, Rollinsford and Newington — so a storm week usually means one truck handling several addresses in Strafford County rather than separate trips.
Nearest hub towns with their own commercial snow pages: Somersworth, Dover, Durham, Portsmouth, Exeter, Concord.
Coverage runs across Rochester and the nearby towns all winter, and capacity is surged into whichever New Hampshire market the storm actually hits.
Most jobs do not stop at one service. Commercial Snow in Rochester often runs alongside crane-assisted snow removal in Rochester, and both get written into one scope rather than billed as separate visits.
